If one pops up in Warwickshire let me know. I can happily go and take a look

.
I shall also say (but you seem to know this) that I would not get held up on mileage, especially if you plan to drive the car and keep it for some time. A chap I know bought another Turbo over mine because of the mileage (with that owner speaking of how low mileage is key) only for it to blow up on him shortly after.
Mine is still a daily to the bloke I sold it to with him doing weekly commutes to Wales and back to the 'Shire (I would not want his petrol bills but at least he's having fun!). I guess that is unfair that comparison but IMO maintenance stands for alot, something which receipts and 'reading' a car (i.e looking at fuel pipes, tyres, suspension, that kind of thing) can give away. I bought my car on 170k and with the way the owner is driving it I reckon it must be heading towards 185k if not higher.
